KNOCKDOWN TABLE.

To all whom it may concern:

Be it known that we, LoUIs GRAUMILLER, HENRY BOSENBERGER, and EDGARBYRON SMITH, citizens of the United States of America, residing atDetroit, in the county of Wayne and State of Michigan, have inventedcertain new and useful Improvements in Knockdown Tables, of which thefollowing is a specification, reference being had there in to theaccompanying drawings.

This invention relates to tables and especially to a stand particularlyadapted for use by surgeons and nurses in the hospital and operatingroom, which is of a knock-down type, whereby it may be taken apart andthe members thrown into a disinfecting bath, and the parts assembledwithout the aid of tools, and is also designed for cafs, dining of thebrackets or standards which support the table. Fig. 3 shows the same inplan and side elevation. Fig. 4 is a view in perspective showing theinterlocking ends of the cross-braces of the standards. Fig. 5 is a planview partially in section showing the ends of the cross braces assembledand secured by a shield. Fig. 6 shows the same in side elevation. Fig. 7is a perspective View of the interlocking shield.

As herein illustrated, an appropriately designed main standard 1 ofmetal has anintegral 11 per horizontal bracket 2 withsquare shoul eredtenons 3 on its extremity halved to engage mating ends 4 of brackets 5in corresponding standards 6, and provided with dowel pins 7 enteringapertures 8 in the other bracket ends. An integral horizontal crossbrace9 near the lower end of the main standard has arms 10 which are halvedand shouldered to mate with the ends 11 of the crossbraces 12 on theother standards, wings 13 on the latter braces having diagonal sides 14abutting against shoulders 15 on the main brace preventing angulardisplacement. The wings 13 and adjacent parts of the arms 10 form ineffect a circular disk when closed together, and a circular shield 16with periph- Specification of Letters Patent.

eral flange 17 notched to slip over the braces, locks them together. Theupper face 18 of each of the tenons 3 and the lower face 19 of eachcorresponding arm 10 are slightly oblique or convergent, so that inassembling the parts, the end 4 of the standard bracket is hooked over adowel pin on the main bracket and the ends of the cross-braces are swunglongitudinally toward each other, the inclined faces acting as wedges todraw the parts firmly to seat. I

A table top 20, preferably of glass, rests on .suitable lugs 21 on thestandards, ears 22 preventing lateral displacement, and a central boss23 on the main bracket affording support for the table center. A lowershelf 24 is placed on retaining ledges 25, and bears centrally on theshield 16.

One of the features of the invention is the location of the metalconnections or joints centrally under the top and shelf so that they are1Well protected from liquids spilled on the tab e.

The parts of the table, when taken down, may be sterilized by immersionin a suitable bath and when withdrawn, are easily dried,

as there are no hinges, pivots, sockets or recesses in which liquid isretained and all the surfaces are exposed for cleaning.

The members are easily assembled and afford solid support for the to andshelves as no weight is carried by the oints, which are subjected tolateral strains only.

What we claim as our invention is 1. A table comprising a plurality ofstandards having horizontal upper brackets and lower cross-bracesextending to a common center line, one of said standards having tenonsand dowel pins on the extremity of its bracket and divergent undercutshouldered arms on the brace, the other standard bracket ends being eachhalved and apertured to interlock with one of said tenons and dowelpins, and the other braces each having a halved end engaging one of theundercut shouldered arms, wings on each brace with oblique sidesabutting the adjacent wings and forming therewith a circular disk, aflanged shield detachably locking said wings together, and a topsupported on the standards above the brackets.

2. A table comprising a plurality of standards .having horizontal upperbrackets and lower cross-braces extending to a common center-line, oneof'said standards having tenons and dowel pins on the extremity 0 itsbracket and divergent .undercut shouldered arms on the brace, the otherstandard bracket ends being each halved and apertured to interlock withone of said tenons and dowel pins, and the other braces each having ahalved end engaging one of the undercut shouldered arms, wings on eachbrace with oblique sides abutting the adjacent wings and formingtherewith a circular disk, a flanged shield detachably locking saidwings together, a top supported on the standards above the brackets anda shelf detachably secured to the standards between the braces andbrackets.

3. A table comprising a plurality of standards having horizontal upperbrackets and lower cross-braces extending to a common center line, oneof said standards having tenons and dowel pins on the extremity of itsbracket and divergent undercut shouldered arms on the brace, the otherstandard bracket ends being each halved and apertured to interlock withone of said tenons and dowel pins and the other braces each having ahalved end engaging one of the undercut shouldered arms, a wing on eachbrace with oblique sides abutting the adjacent wings, and formingtherewith a circular disk, a flanged shield detachably locking saidwings together, a top removably secured on the standards above thebrackets and ashelf detachably secured to the standards between thebraces and brackets, the upper face of each tenon and lower face of thecorresponding arm on the first standard being longitudinally convergentand the mating faces of the bracket and brace ends of the otherstandards being correspondingly beveled, said coacting faces beingadapted to draw the parts to seat when assembled.

4. A table comprising a plurality of standards having horizontal upperbrackets and lower cross-braces extending to a common center line, oneof said standards having tenons and dowel pins on the extremity of itsbracket and divergent undercut shouldered arms on the brace, the otherstandard bracket ends being each halved and apertured to interlock withone of said tenons and dowel pins, and the other braces each having ahalved end engaging one of the undercut shouldered arms, a wing on eachbrace with oblique sides abutting the adjacent Wings, and formingtherewith a circular disk, a circular shield having a peripheral flangeadapted to close over and lock the wings together, a top removablysecured on the standards above the brackets and a shelf detachablysecured to the standards between the braces and brackets.

5. A table comprising a plurality of standards having horizontal upperbrackets and lower cross-braces extending to a common center line, oneof said standards having tenons and dowel pins on the extremity of itsbracket and divergent undercut shouldered arms on the brace, the otherstandard bracket ends being each halved and apertured to, interlock withone of said tenons and dowel pins, and the other braces each having ahalved end engaging one of the undercut shouldered arms, a wing on eachbrace with oblique sides abutting the adjacent wings and formingtherewith a circular disk, a flanged shield detachably locking saidwings together, lugs on the outer upper extremities of each standardprovided with marginal ears, a top plate resting on said lugs betweenthe ears, ledges on the standards between the braces and bracketsprovided with marginal ears and a shelf on the ledges between the ears.

In testimony whereof we aflix our signatures in presence of twowitnesses.
